     mountd -- service remote NFS mount	requests

     mountd [-2dlnr] [exportsfile]

     The mountd	utility	is the server for NFS mount requests from other	client
     machines.	It listens for service requests	at the port indicated in the
     NFS server	specification; see Network File	System Protocol	Specification,
     RFC1094, Appendix A and NFS: Network File System Version 3	Protocol
     Specification, Appendix I.

     The following options are available:

     -2	     Allow the administrator to	force clients to use only the version
	     2 NFS protocol to mount file systems from this server.

     -d	     Output debugging information.

     -l	     Cause all succeeded mountd	requests to be logged.

     -n	     Allow non-root mount requests to be served.  This should only be
	     specified if there	are clients such as PC's, that require it.  It
	     will automatically	clear the vfs.nfsrv.nfs_privport sysctl	flag,
	     which controls if the kernel will accept NFS requests from	re-
	     served ports only.

     -r	     Allow mount RPCs requests for regular files to be served.	Al-
	     though this seems to violate the mount protocol specification,
	     some diskless workstations	do mount requests for their swapfiles
	     and expect	them to	be regular files.  Since a regular file	cannot
	     be	specified in /etc/exports, the entire file system in which the
	     swapfiles resides will have to be exported	with the -alldirs

	     Specify an	alternate location for the exports file.

     When mountd is started, it	loads the export host addresses	and options
     into the kernel using the mount(2)	system call.  After changing the ex-
     ports file, a hangup signal should	be sent	to the mountd daemon to	get it
     to	reload the export information.	After sending the SIGHUP (kill -s HUP
     `cat /var/run/`), check the syslog output to see	if mountd
     logged any	parsing	errors in the exports file.

     If	mountd detects that the	running	kernel does not	include	NFS support,
     it	will attempt to	load a loadable	kernel module containing NFS code, us-
     ing kldload(2).  If this fails, or	no NFS KLD was available, mountd exits
     with an error.

     /etc/exports	  the list of exported file systems
     /var/run/  the pid of the currently running mountd
     /var/db/mountdtab	  the current list of remote mounted file systems

     nfsstat(1), kldload(2), exports(5), nfsd(8), rpcbind(8), showmount(8)

     The mountd	utility	first appeared in 4.4BSD.
